It will be understood, of course, that each section of my improved pipeor conduit is separately constructed, concrete or other com ositematerial 13 being applied to or mol ed around the skeleton or frame ofthe section of the structure, leaving the ends of the strips orlongitudinally-disposed members 4 free, so as to enable the couplingtogether of successive sections of the pipe or conduit in the mannerjust above explained. In this Way when long" lines of the pipe orconduit are to be formed it is apparent that the naked coupled portionsof the strips or longitudinally-disposed members 4 of the successiveskeletons or frames at the joints of the sections have applied theretoeither concrete or other composite material to complete the structure.

I thus derive a pipe or conduit of the character specified which iscapable of withstanding'enormous internal and external pressure andwhich is reinl'prccd throughout the entire length thercofin such manneras to adapt the structure for use either a culvert or drain-pipe, aswell as for other purposes.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A conduit comprising sections of compositionmaterial, having i'netallie frames embedded therein,embodyingJpngitudinal membersmenstructed at one 0 their ends With slotsand-provided at' their other ends withjaws having opposite slotstherein, registering with said first named slots, and Wedges driven intoeach set of registering slots for securing said sections together.

2. A conduit comprising sections 01' composition material, havingmetallic structures embedded therein, said structures comprising spacedcircumt'erent-ially-disposed members, and longitudinally-disp0sedmembers connected to the circuiniercntially-disposed members, saidlongitudinally-disposed mem bers having at one end a longitudinal slot,and 'at the other jaws spaced radially from each other for receiving theopposite end of the corresponding member of the preceding section, eachof said jaws having a longitudinal slot, and a wedge traversing thealined slots, whereby to secure the structures together.

3. A conduit comprising sections oi composition material, havingmetallic l'rames embedded therein, said frames comprising longitudinalmembers having at one end a slot and at the other end radially-spaccdjaws each provided with a slot and adapted to receive therebetween theopposite end of the corresponding longitudinal member ol the precedingsection, and wedges traversing the slots for retaining the parts inposition.
